' DEVICE FOR VENTILATING CARS OR OTHER VEHICLES.

SPECIFICATION forming part of Letters Patent No. 621,627, dated March 21, 1899.

Application filed May 28, 1898. Serial No. 682,043. (No model.)

To all whom it may conccrnf Be it known that I, LAWRENCE WHITE, of Little Rock, in the county of Pulaski and State of Arkansas, have invented a new and Improved Device for Ventilating Cars or other Vehicles,of which the followingis a full, clear, and exact description.

The object of my invention is to provide a device especially adapted for ventilating cars, om nibuses, or other vehicles, the device being so constructed that in operation it will produce a thorough ventilation without admitting dust, cinders, &c., to the interior of the car or other vehicle.

A further object of the invention is to con struct a device of the character above described in a simple, durable, and economic manner and to provide for the device being operated by the current of air induced by the travel of the Vehicle to which it is applied, the propelling mechanism of the device being of such a nature that it will automatically accommodate itself to changes of position of the vehicle to which it is applied.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter'fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both figures.

Figure 1 is a vertical section through a portion of a vehicle-top, showing the device ap plied, the device being mainly in side elevation, parts of the device, however, being shown in section; and Fig. 2 is a plan view of the device as shown in Fig. 1.

A represents the top of a car or other vehicle, and B the interior thereof. A bearing 10 is secured in the top of the vehicle, extending within the vehicle and also beyond the outer face of the top, and the said bearing is preferably provided within the vehicle with a flange 11. A cover 12, preferably domeshaped, is secured to the top of the vehicle by the flange 11 of the bearing, the bearing 10 being preferably passed through the said cover, and a cage 13, of reticulated or perforated material, is attached to the said cover 12, the cover beingpreferably circular and the cage of similar form. A shaft 14 is journaled in the bearing 10, and the said shaft extends a suitable distance above and below the top of the vehicle, as shown in Fig. 1. A vane O is located above the top of the vehicle, and the said vane is preferably provided with an upper and a-lower horizontal arm,- the arms being designated as 15 and 16. The shaft 14 passes loosely through both of these arms, and the lowerarm l6 rests upon the upper end of the bearing 10. The vane is prevented from moving upward by securing a collar 17 on the shaft 14 above the lower arm 16 of said vane.

A hearing 19 is erected longitudinally upon the vane O, and in the said bearing a shaft 20 is mounted to turn, which shaft at the outer or free end of the vane is provided with an attached propeller-wheel or a wind-wheel 21, while at the inner end of the shaft 20, between the arms 15 and 16 of the vane, a beveled gear 22, is secured, which meshes with a similar gear 23, secured upon the shaft 14.

A fan D is located within the cage, the fan being secured to the lower end of the shaft 14. This fan preferably consists of a hub 24 and blades or plates 25, which are screwed into the hub or otherwise adj ustably secured thereto, so that sundry of the blades or plates may be carried out of action when desired. A collar 26 is secured upon the shaft 14 between the lower end of the bearing 10 and the hub of the fan D. One end of a cord 27 is secured to the hub of the fan, the said cord being passed up through an opening in the collar 26 and out through an opening in the cover 12, over a pulley 28, as shown in Fig. 1, and from thence downward to within convenient reach of the floor of the car.

In operation the vane C will automatically shift according to the direction in which the car is traveling, so that the current of air induced by the travel of the car or vehicle will revolve the wind-wheel or propeller 21, whereby the shaft 14 is revolved, and consequently the fan D within the car. Under such an arrangement the interior of the car may be thoroughly ventilated without introducing dust into the car or cinders or other extraneous matter. When it is desired to stop the fan, it is simply necessary to pull downward upon the cord 27 whereupon the fan and shaft 14 will be raised, carrying the gear 23 out of mesh with the gear 22 on the drive-shaft, as shown in dotted lines in Fig. 1.

This device is exceedingly simple, durable, and economic and may be readily and conveniently applied to any character of vehicle.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A ventilating device for vehicles, consistextends, the cage being adapted to be located within the vehicle, a fan secured to the said shaft, and mounted to revolve within the said cage, and means, substantially as described,

.for disconnecting the shaft from driving connection with the wind-propeller, as set forth.

3. In a ventilating attachment for vehicles, the combination, with a bearing adapted for attachment to the vehicle, a shaft mounted in the said bearing and arranged to extend without and within the vehicle, a vane loosely mounted on the shaft, a drive-shaft carried by the vane, a wind-propeller secured to the said drive-shaft, and a gear connection between the drive-shaft and the main shaft, of a fan secured to the lower portion of the main shaft, and means, substantially as described, for raising and lowering the said main shaft, for the purpose set forth.

4:. In a ventilating attachment for vehicles, the combination, with a bearing adapted for attachment to a vehicle, a shaft mounted in the said bearing and arranged to extend without and within a Vehicle, a vane loosely mounted on the shaft, a drive-shaft carried by the vane, a wind-propeller secured to the said drive-shaft, and a gear connection between the drive-shaft and the main shaft, of a cage into which the lower end of the main shaft extends, a fan secured to the lower end of the main shaft, the blades of the fan being adjustable, and means, substantially as described, for raising and lowering the main shaft, for the purpose specified.

5. A ventilating device for vehicles consisting of a shaft loosely mounted in a bearing in the vehicle and carrying a fan and extending to the outside of said vehicle, a vane loosely mounted upon said shaft and carrying a windwheel operatively connected with said shaft, and means for raising said shaft in its bearing whereby to disconnect it from operation with said wind-wheel, as described.
